Description
Technical field
The utility model relates to the oil seismic exploration rig, and particularly the hydraulic system of exploratory drilling rig is a kind of two closed type hydraulic systems of exploratory drilling rig.
Background technique
At present, mountain region exploratory drilling rig hydraulic system generally adopts open type hydraulic system both at home and abroad.Open type hydraulic system mainly is made up of an open type volume adjustable hydraulic pump, load-sensitive valve, unit head motor, lifting motor and fuel tank, hydraulic oil provides hydraulic power by the open type volume adjustable hydraulic pump, after the shunting of load-sensitive valve, supply with the unit head motor respectively and promote motor.
Owing to through the load-sensitive valve, increased the hydraulic pressure loss in the middle of the hydraulic oil, the hydraulic system heating.When one of them oil hydraulic motor is in the working state of high-pressure low-flow, and another motor is when being in low pressure and mass flow, the power of hydraulic system generally mates by high-pressure high-flow, and the actual power consumption of two oil hydraulic motors is more much smaller than mesh power, so the power utilization of motor is lower.
Along with the increase of drilling depth, drilling hydraulic system consumption power also increases thereupon, and existing hydraulic system can not adapt to, and needs to optimize hydraulic system, improves the engine power utilization ratio, reduces the pressure loss, reduces system's heating value.
The model utility content
The purpose of this utility model is: a kind of two closed type hydraulic systems of exploratory drilling rig are provided, can provide reliable hydraulic power for exploratory drilling rig, adapt to the increase of drilling depth, the requirement that drilling hydraulic system consumption power increases.Overcoming existing hydraulic system needs the engine power height, utilizes rate variance, the deficiency that the pressure loss is many.
The technical solution adopted in the utility model is: two closed type hydraulic systems of exploratory drilling rig, mainly form by duplex oil hydraulic pump, unit head motor, pilot valve, equilibrium valve, lifting motor and fuel tank.The working hole A of duplex oil hydraulic pump front pump, B mouth connect A, the B mouth of unit head motor respectively; The working hole A1 of pump, B1 mouth connect A, the B mouth of equilibrium valve respectively behind the duplex oil hydraulic pump, and delivery outlet C1, the C2 of equilibrium valve connects A, the B mouth that promotes motor respectively.The inlet port S of duplex oil hydraulic pump front pump is connected with fuel tank; Control mouth a, the b of duplex oil hydraulic pump front pump is connected with control mouth d1, the d2 of preceding pilot valve; Control mouth a1, the b1 of pump connect control mouth d3, the d4 of back pilot valve behind the duplex oil hydraulic pump.The P mouth of preceding pilot valve is connected with the p mouth of duplex oil hydraulic pump front pump; The oil return of preceding pilot valve converges at valve inner with the oil return of back pilot valve, is connected to fuel tank by the T mouth.
The summary working principle helps to understand the utility model.Duplex oil hydraulic pump front pump directly drives the unit head motor, by pump delivery before the preceding pilot valve 2 adjusting duplex oil hydraulic pumps, promptly regulate flow by the unit head motor, thereby the rotating speed of control unit head motor, reasonable selection through the unit head motor, can make the highest output torque of motor reach 1550N.m, maximum speed reaches 150r/min, has improved drilling efficiency; Pump links to each other with the lifting motor through equilibrium valve behind the duplex oil hydraulic pump, pump delivery behind the back servocontrol valve regulation duplex oil hydraulic pump, i.e. and control promotes the lifting speed of motor.Because pump does not disturb mutually behind duplex oil hydraulic pump front pump, the duplex oil hydraulic pump, so can make the power of motor be used for a certain motor separately, or make two motors all keep big flow high pulling torque, satisfy and creep into and promote the efficient requirement, make full use of engine power, improved drill capacity and efficient.Simultaneously, because the forward and backward pump of duplex hydraulic pressure is directly distinguished drive motor, the pressure loss in the middle of having reduced has reduced energy consumption, has alleviated system's heating.
The beneficial effects of the utility model: two closed type hydraulic systems of the utility model exploratory drilling rig can provide reliable hydraulic power for exploratory drilling rig, and have improved the engine power utilization ratio, have improved drilling efficiency, have reduced energy consumption, have alleviated system's heating.
